Patented Feb. 3, 1931 UNITED ANDREW CHRISTIAN HANSON, on RACINE,wIsooNsIN CONTROLLING DEVICE FOR SHADES I Application filed July 20,1928. Serial No. 294,069(

This invention relates to improvements in controlling devices forshades.

It is a primary object of the present invention to provide a curtain orshade roller fixture by which the curtain is retained at any desiredheight, and in which the need of a spring in the curtain roller iseliminated.

A further object of the invention is to provide a curtain roller fixturewhich when 1 applied to the end portion of a curtain roller, will verysatisfactorily balance and tension the curtain at different positions ofad ustment. r

A further object of the invention is to provide a controlling device forcurtains or shades which holds the shade in any adjusted position and inwhich the tension of the shade in any of its movements is not varied.

A further object of the invention is to provide a curtain roller fixturehaving improved friction brake means for holding the roller in anyposition, said brake means being adjustable as to the amount of frictionto slut the requirements of various curtalns.

A further object of the invention is to provide a controlling device forshades which is simple in construction, inexpensive to manufacture andinstall, strong and durable, and

well adaptedfor the purposes described.

With the above and other objects in view, the invention consists of theimproved ourtain roller fixture, and its parts and combinations as setforth in the claims and all equivalents thereof.

In the accompanying drawing, in which the same referencecharactersindicate the same parts in all of the views:

Fig. 1 is a front view of a window and shade therefor mounted on aroller, one end portion of the roller being engaged by the improvedcontrolling fixtures;

Fig. 2 is a side view on a larger scale of the curtain roller fixturelooking at the roller engaging portion; 7

Fig. 3 is a sectional view taken on the line 33 of Fig. 4;

Fig. 4 is a sectional View taken on the line 4-4 of Fig. 2, a portion ofthe curtain roller being shown in attachment with the device;

Fig. 5 is a view showing the opposite side of the device from that shownin Fig.2, part of the casing being broken away;

Fig. 6 is a perspective View of the bracket and outer casing; and V:Fig. 7 is a perspective view of the drum.

Referring now more particularly to the drawing it will appear that thenumeral 8 designates a window casing and'9 a window sash mountedtherein, and adapted to be covered bya shade or curtain 10 which issecured at its upper end portion to and adapted .to be rolled about aroller 11 horizontally mounted at the upper portion of the casing. Oneend portion of said rolleris journaled in a bracket- 12 of ordinaryconstruction, while the other end portion has a sleeve 13 securedthereto by pins 14. The outer end of the sleeve 15. is smaller indiameter than the main portion and has a closed end 16 whichis providedwith'a pair of openings 17. f The openings are engaged by lugs 18 whichare stamped from and project out of the outer end of a drum. 19 formingpart of the improved rollercontrolling fixture, the latter beingindicated generally by the numeral 20. 1

The controlling. fixture comprisesan outershell '21 whichis-open atoneside and which has its other side stamped inwardly to form a cylindricalprojecting portion 22 and also forming a recess 23 in the side of thecasing. Within the casing and surrounding the cylindrical portion 22 isa washer 24.

I The drum 19 is open at one end, the said opening fitting over theprojecting portion 22. The outer periphery of the drum is formed withside flanges '25 between which a tape 26 is wound. Oneset of flanges areadapted to bear against the washer 24.

. The closed endof the drum' in addition to having lugslS extendingtherefrom is provided with a central opening 27 through which a bolt 28-eXtends. .The bolt alsoextends through an opening 29 in the central partof. the cylindrical projecting portion 22. On the end of the bolt is alock washer. 30 and a pair of. nuts 31. It may readily be seen that bytightening the bolt the drum may be caused to engage the Washer-24 withany 1 desired degree of friction between the two.

The casing is provided with an opening 32 through which the tape 26 isadapted to extend. The casing is also formed with a suitable bracket 33having openings 3 1 by which it may be secured to the window frame. Itis obvious that the-exact form of bracket may be varied to meet therequirements of various types of windows. The bracket may be soconstructed that the device may be secured to the inner edge of thewindow frame instead of the outside of the frame as shown.

In use, a curtain is mounted, as at Fig. 1 with the end of its rollercontaining the s eeve 13 engaged by the lugs 18 of the drum 19 of thefixture. The shade may be lowered by pulling it downwardly with theordinary shade cord and it is retained in any adjusted position by thefriction brake means comprising the washer and means for causing thedrum to bear against said washer. When the curtain is lowered the tape26 is wound up on the drum, and to raise the curtain the tape is pulleddownwardly, unwinding the drum-and turning the rollerto wind'thecurtainthereon. As ,mentionechthe degree of pressure exerted on thewasher may bevaried by adjusting the bolt 28. For a large heavy curtain,it will be necessary to have the drum engaging the washer withconsiderably more pressure than for a small light weight curtain. Thescrew may be set when the fixture is installed and it is unnecessary tovary the adjustment thereafter.

From the foregoing description it will be seen that the improvedcontrolling device for curtains or shades is both simple and novel andis well adapted for the purposes described.

What I claim is:

1. A curtain roller fixture comprising a cylindrical casing having anopenend and a and adjustable means for causing said drum to frictionallyengage the washer.

3. A curtain roller fixture comprising a cylindrical casing having anopen end and a closed end, said closed end being stamped inwardly toform a cylindrical projection within the casing and to form a recess onthe outside, said projection having a perforation therein, a drum havingan open end and a closed end revolubly mounted within said casing, andhaving its open end positioned around said cylindrical projectingportion of the casing, said closed end of the drum beingformed withmeans for engaging an end portion of a curtain roller and being alsoformed with a perforation, a bolt extending through the perforationofthe drum and of the projecting portion of the casing, and a nutthreaded on said bolt within the recess formed by theprojecting portion,said In testimony whereof, I afliX my signature.
